Patent JP-S63294298-A (JP)
Title: Excitation control device
Inventor: SAIMARU KENJI
IPC: H02P9/30
Filed: 1987-05-26
Abstract: PURPOSE:To dispense with a field circuit breaker and a discharging resistor, by forming a discharging circuit of a field winding by the use of a thyristor for initial excitation in stopping the excitation of a synchronous generator. CONSTITUTION:When a stopping command is given, an excitation control device turns OFF the gate signal to a thyristor 7 and cuts off a power breaker 4. If the voltage across both terminals of a thyristor 9 for initial excitation, i.e. the voltage across a field winding 2 is over the set value, a voltage detector 8 will give the signal to a pulse generator 11. The thyristor 9 for initial excitation is thereby fired to form a discharging circuit of the field winding 2, so that the electromagnetic energy is attenuated. In this way, the discharging resistance and the field circuit breaker are dispensed with.

Title: Method and device for evaluating silicon wafer
Inventor: OGITA YOICHIRO
IPC: H01L21/66
Filed: 1993-05-28
Abstract: PURPOSE:To enable the surface of a semiconductor wafer and the crystallinity of a surface crystal layer to be measured through a non-destructive method by a method wherein the surface of a wafer is irradiated with impulse light and electromagnetic waves at the same time, and the reflected electromagnetic waves are detected. CONSTITUTION:A position P on the surface a semiconductor wafer is irradiated with impulse light 4 large in absorption coefficient, as it is kept irradiated with electromagnetic waves 2. At this point, the reflected waves 3 of the probing electromagnetic waves 2 are detected. The reflected waves 3 of the probing waves 2 are modulated due to a so-called photoconductivity attenuation change caused by an increase in photoconductivity due to light carrier excited in crystal and a decrease in photoconductivity due to recombination after quenching. Therefore, the reflected waves 3 of the probing waves 2 are detected, whereby a photoconductivity attenuation change can be obtained. This photoconductivity change can be obtained through such a manner that the reflected waves 3 are high-speed detected and observed by a high-speed waveform observing equipment. The surface of a wafer and the properties of a surface crystal layer can be evaluated basing on the obtained photoconductivity change.

Title: Non-utility generator utilizing rotation and revolution of the earth
Inventor: YAMADA TAKASHI
IPC: H02K53/00
Filed: 1998-04-02
Abstract: PROBLEM TO BE SOLVED: To provide a generator which is capable of generating a high output with a small amount of input. SOLUTION: A private generator effectively utilizes the rotation and revolution of the earth and makes oscillating motions to maintain its rotation by applying a spinning top. The generator generates electric power by utilizing the rotating speeds of the top or a rotating ball. Although some energy is required at the starting of the generator, the high-speed rotation of the rotating ball can be maintained with a small amount of oscillations, because a force tends to work toward the center, when the rotating speed of the rotating ball becomes higher. Therefore, the output of the generator increases while the input decreases. The output can be returned to the input, and a considerably high watt value can be outputted when the capacity of the generator is changed.

Filed: 1997-05-01
Abstract: PROBLEM TO BE SOLVED: To allow the reader to read an image in a stable state at all times by allowing the reader to be provided with a read control means that reads image information to be read for an intermittent operation period of a read means at a constant speed operation in advance and stores the read information to a storage means. SOLUTION: In the case that a storage section 3 is fully occupied by stored image data and reading is to be stopped temporarily, a drive discrimination section 5 discriminates in advance an intermittent operation condition. A read control section 6 acquires the discrimination result, and allows a read section 1 set to a constant speed to read data of an area for an intermittent operation period of the original for a 1st reading at first and stores the read data to the storage section 3. While an image read section 4 extracting the stored image data, the control section 6 executes 2nd reading immediately to allow the read section 1 to read the image data from the start of the original till the area equivalent to the intermittent period at a constant speed, stores the data to the storage section 3, and the image read section 4 extracts the data. Thus, the image information of the original is entirely read and stored in the storage section 3 and the image read section 4 extracts the image.
